Scanning electron microscopy, or SEM, produces detailed, magnified images of an object by scanning its surface to create a high resolution image. SEM does this using a focused beam of electrons. The resulting images show information about what the object is made of and its physical features. The instrument which obtains this information about composition and topography
Scanning Electron Microscope (SEM) from Carl Zeiss. More Details. Location: Level 5 KBC - C Building - Map to KBC can be found here. Technical Specification: - Accelerating voltage: 200 V - 30 k - Electron emitter: LaB6 crystalResolution (optimal WD): 9 nm @ 1 kV; 2 nm @ 30 kV A clip for the Acme School of Stuff "Acme Shorts" with David Stringer on how a scanning electron microscope works. In scanning electron microscopy, the electron beam scans the sample in a raster pattern. First, electrons are generated at the top of the column by the electron source. These are emitted when their thermal energy overcomes the work function of the source material.
Photons are generated when activated electrons collide with a Scintillator.

Scanning electron microscopy (SEM) is widely used to qualitatively examine surface texture of tribological specimens using either secondary electron (SE) or topography modes. The SEM images are characterized by high resolution (up to 10 [nm]) and large depth of field.
